PS WP Multi Domain

Vincent Robic

<p>This plugin updates all URLs in the database after moving your site from one domain to another. It is useful for switching between development, testing and production stages.</p>
<p>Why this plugin ? WordPress stores absolute URLs in :</p>
<ul>
<li>posts (including pages and custom post types), drafts</li>
<li>excerpts</li>
<li>medias</li>
<li>custom fields</li>
<li>options (including ‘siteurl’ and ‘home’, in wp_options table)</li>
<li>GUIDs (only for development)</li>
</ul>
<p>When moving your website to a new domain, all these links will point to your old domain name and become outdated.</p>
<h3>Prerequisite</h3>
<p>Before moving the website, consider making a backup of the database. Then, once the site has been moved, you will need to manually update ‘siteurl’ in the ‘wp_options’ table, in order to access the WordPress Administration panel.<br />
